Features: 6x 1A can be output in paralleled to increase current. Lithiums battery charging module 4056 is independent of 6 groups in paralleled, with each group outputting 1000ma. Supports charging 6 batteries together for 5V input circuit. The output shares the same ground and can be connected in paralleled to increase the output current. With status indicator light, more convenient to use. Specifications: Material:PCB Input voltage: 5V-6V (exceeding the voltage can cause damage) Output voltage: 4.2V (± 1%) Output current: 1A Status indicator: LED charging red light, fully charged to green (hangings green light on or flashing green light) 1.The input cannot be reversed or overpressure, and the output cannot be reversed to the battery, otherwise it will cause chip damage. 2.The output is common to the ground, and multiple in paralleled connections can be used to increase the output current, but the battery cannot be charged in series. 3.This product does not include a transform, and the customer comes with a 5V 6A power transform. Package Includes: 1x Lithiums Battery Charging Module note: Please allow 1mm errors due to manual measurement. Due to the difference between different monitors, the picture may not reflect the actual color of the item.
